2. The antenna of claim 1, wherein the activating agent comprises moisture.
3. The antenna of claim 1, wherein the activating agent comprises an acid and/or base detecting material.
4. The antenna of claim 1, wherein the activating agent comprises a chemical detecting material.
5. The antenna of claim 1, wherein the hydrogel material is configured to expand upon interaction with the activating agent.
6. The antenna of claim 1, wherein the hydrogel material is arranged in a powdery state on a base material.
7. The antenna of claim 6, wherein the base material comprises a fabric.
8. The antenna of claim 6, wherein the hydrogel material is arranged in a shape of an RFID antenna.
9. The antenna of claim 1, further comprising a metal antenna in communication with the non-metal antenna.
11. The sensor of claim 10, wherein the RFID tag is a passive RFID tag.
12. The sensor of claim 11, wherein the RFID tag is configured to vary impedance in response to sensing of an activating agent.
13. The sensor of claim 10, wherein the power to turn on the wireless data communication IC derives from a reader that is separate from the sensor, where the non-metal antenna receives electromagnetic energy from the separate reader and uses this energy to drive and transmit the power transmitted to turn on the wireless data communication IC when the non-metal antenna is active.
15. The antenna of claim 14, wherein the power to turn on the wireless data communication IC derives from a reader that is separate from the sensor, where the antenna receives electromagnetic energy from the separate reader and uses this energy to drive and transmit the power transmitted to turn on the wireless data communication IC when the antenna is active.
